Abstract
The NTERA2 cl D1 (NT2) cell line, derived from human teratocarcinoma, exhibits similar properties as embryonic stem (ES) cells or very early neuroepithelial progenitors. NT2 cells can be induced to become postmitotic central nervous system neurons (NT2N) with retinoic acid. Although neurons derived f...

Abstract
We also demonstrate that two key transcription factor genes known to be regulated by Wnt signaling and to be vital for the generation and function of dopaminergic neurons; i.e., Lmx1a and Engrailed 1, are down-regulated in the HPRT knockdown SH-SY5Y cells. In addition to the Wnt signaling aberration...

Abstract
We quantified and enriched ALDH1(+) cells within HNSCC cell lines and subsequently characterized their phenotypical and functional properties like invasion capacity and epithelial-mesenchymal transition (EMT). Spheroid culture enriched CSC from five HNSCC cell lines by up to 5-fold. In spheroid-deri...

Abstract
We address these issues by studying five populations: the popular Sprague-Dawley strain, sub-strains of Long-Evans and Wistar rats, and two lines derived from crosses between the Long-Evans and Wistar sub-strains. Using three independent techniques - variance analysis, linear modelling, and unsuperv...

Abstract
We report the regulatory response of C. crescentus to carbon starvation, based on combined high-throughput proteome and transcriptome analyses. Our results identify cell cycle changes in gene expression in response to carbon starvation that involve the prominent role of the FixK FNR/CAP family trans...

Abstract
We discuss three mechanisms through which histone methylation can be removed from the chromatin template. We describe how these "erasure" mechanisms are linked to pathways that are known to be misregulated in diseases, such as cancer. We further describe how errors in the removal of histone methylat...

Abstract
We have used pathway-restricted gene expression profiles derived from RAS oncogene-transformed cells and from RAS-expressing cancer cells to identify regulators downstream of the MAPK pathway.We describe the role of epigenetic regulation exemplified by the control of several immune genes in generic...

Abstract
Glial cells missing 2 (Gcm2) is a master regulatory gene of parathyroid gland development, and it is exclusively expressed in the parathyroid gland. Diagnostic application of anti-Gcm2 antibody has not been reported yet. In this study, a total of 58 cases of parathyroid lesions including 40 adenomas...

Abstract
We compared two commonly used approaches to enrich for methylated DNA regions of the genome, namely methyl-DNA immunoprecipitation (MeDIP) that is based on enrichment with antibodies specific for 5'-methylcytosine (5MeC), and capture of methylated DNA using a methyl-CpG binding domain-based (MBD) pr...

Abstract
We present an introduction to the structure and function of nuclear receptors, specifically the estrogen, androgen, glucorticoid, peroxisome proliferator, steroid, thyroid and vitamin D receptors, and a discussion of the state-of-the-art of induced fit approaches for the nuclear receptor family....

Abstract
Four and a half LIM domains protein 1 (FHL1) and FHL2, as the name suggests, contain four and a half LIM domain binding proteins. Proteins in this family capable of interacting with many types of proteins, including structural proteins, kinases, and several classes of transcription f...

Abstract
We used bioinformatic analysis of publicly available data in order to systematically identify the genes involved in resistance to cytotoxic effects of these two drugs in the NCI60 cell line panel. We used the pharmacological data available for all the NCI60 cell lines to classify simvastatin or lova...

Abstract
Copy number variations (CNV) within the genome are extremely abundant. In this closeup, Canales and Walz discuss how CNV are associated with normal variation, genomic disorders, genome evolution, adaptive traits and how the use of a novel screen described by Ermakova et al in this is...

Abstract
We used in situ hybridization to screen numerous expression patterns of the TFs involved in the development of the mouse thymus. More than 400 members, including unique TFs and some transcription co-factors, were tested. Among the screened TFs, 160 were found to be expressed in the thymus after E15....

Abstract
Recent advances in pancreas organogenesis have greatly improved the understanding of cell lineage from inner cell mass to fully differentiated β-cells. Based upon such knowledge, insulin-producing cells similar to β-cells to a certain extent have been generated from various cell so...

Abstract
We develop a novel computational method that combines accurate quantification of 2D limb bud morphologies and growth modeling to analyze mouse clonal data of early limb development. Firstly, we explore various tissue movements that match experimental limb bud shape changes. Secondly, by comparing co...

Abstract
Hypospadias is a common congenital anomalies, yet its molecular basis remains unknown. Recent studies have linked perturbations in the Hedgehog signaling pathway to hypospadias. However, the expression of Sonic hedgehog (Shh) has not been reported during genital development. Immunohi...

Abstract
We investigated possible cooperative deregulation of microRNAs (miRNAs) and transcription factors (TFs) in glioblastoma, under the hypothesis that miRNAs and TFs might have a combinational regulatory effect on glioblastoma genes. We searched glioblastoma-specific regulatory networks by integrating g...

Abstract
We show sheep fibroblasts can be reprogrammed to pluripotency by defined factors using a drug-inducible system. Sheep iPSCs derived in this fashion have a normal karyotype, exhibit morphological features similar to those of human ESCs and express AP, Oct4, Sox2, Nanog and the cell surface marker SSE...

Abstract
We found that expression of MAGE I proteins, MAGE-A3 or MAGE-C2, relieved repression of a reporter gene by ZNF382, a KZNF with tumor suppressor activity. ChIP of MAGE I (-) HEK293T cells showed KAP1 and H3me3K9 are normally bound to the ID1 gene, a target of ZNF382, but that binding is greatly reduc...

Abstract
We systematically queried the Saccharomyces cerevisiae proteome for Prp19 WD40 domain interaction partners by two-hybrid analysis. We report that in addition to S. cerevisiae Cwc2, the splicing factor Prp17 binds directly to the Prp19 WD40 domain in a 1:1 ratio. Prp17 binds simultaneously with Cwc2...

Abstract
We report that silencing of the fission yeast mating-type cassettes, which are located in a well-characterized heterochromatic region, is hardly affected in cells lacking the H3K9 methyltransferase Clr4. We document the existence of a pathway parallel to H3K9me ensuring gene repression in the absenc...
